Taking a classical approach to psychoacoutstics, Introduction to Normal Auditory Perception guides students toward a basic understanding of hearing science and theory. The book explores the germinal research published in the field of auditory perception and then clearly interprets the findings which have formed the foundations of modern auditory theory. Complex theories are broken down for easy comprehension. Starting with the basic principles of acoustics, the text moves through seminal experiments in psychoacoustics regarding the role of stimulus intensity, frequency, and duration on fundamental auditory perceptions. Basic principles of binaural listening are also covered.
